    摘要: This disclosure describes techniques for improving mode selection decisions during the encoding of macroblocks (or other blocks) of multimedia frames of a multimedia sequence. During motion estimation, the encoding modes for macroblocks can be determined so that a desirable encoding rate and acceptable levels of distortion (i.e., acceptable rate-distortion) can be achieved. The techniques may include selecting a set of multimedia coding modes between at least two sets of possible multimedia coding modes for a macroblock of a multimedia frame based on a detail metric associated with the macroblock and mode information associated with neighboring blocks to the macroblock.

    摘要: This disclosure describes techniques for video coding rate adaptation to reduce packetization overhead. The video coding rate controls the number of coding bits allocated to a segment of encoded video, and hence the length of the encoded video segment. Differences between the length of the encoded video segment and the cumulative length of a series of packets used to encode the video segment result in unused packet space within the last packet in the series. This unused packet space is typically filled with padding bits. In accordance with the disclosure, the video coding rate is adjusted for a segment of digital video so that the encoded video more closely fits within the series of packets, thereby reducing the number of padding bits required by the last packet.

    摘要: Embodiments include systems and methods of improving processing in a decoder in a multimedia transmission system. Multimedia data may include one or more of motion video, audio, still images, or any other suitable type of audio-visual data. One embodiment includes a system and method of parsing fixed and variable length codes from a bit-wise stream of multi-media data by maintaining and reading the data in a processor aligned (e.g., word aligned) way. Another embodiment includes a system and method of decoding variable length codes, particular as received from such a variable length code using multiple levels of decoding tables to speed up decoder table lookup.
